Purpose: Recombinant tumor necrosis factor-alpha (TNF-α) has been utilized as an antineoplastic agent for the treatment of patients with melanoma and sarcoma. It targets tumor cell antigens by impressing tumor-associated vessels. Protein purification with affinity chromatography has been widely used in the downstream processing of pharmaceutical-grade proteins. Methods: In this study, we examined the potential of our produced anti-TNF-scFv fragments for purification of TNF-α produced by Raji cells. he Raji cells were induced by lipopolysaccharides...
